N76269 (cn 31588/966) The coldest night that I have ever spotted! It was a snowy and cold day in Houston as you can see by the snow on the wings and fuselage. Flights were having to be de-iced, which was taking about 1 1/2 hours. This flight was ready to taxi to the de-icing area. My friend Nate and myself waited patiently in 30 degree weather for about 2 hours to catch Lufty 441 which was running about 6 hours late, only to have the flight cancelled!
